Abstract

Selon ce procédé, on découpe une électrode-pièce 2 au moyen d'une électrode-outil 1 en forme de fil, on fait passer des impulsions successives de courant dans l'espace d'étincelage compris entre le fil 1 et la pièce 2, on déplace longitudinalement ce fil 1 dans la zone 3 d'usinage en le soumettant à une force de traction déterminée. La résistance électrique du fil est mesurée dans la partie de ce fil 1 qui traverse la zone 3 d'usinage, et le courant d'usinage et/ou la force de traction exercée sur ce fil 1 dans cette zone 3 sont ajustés de manière à maintenir cette résistance électrique à des valeurs prédéterminées. Ce réglage assure un contrôle permanent des contraintes mécaniques et thermiques exercées sur le fil 1 tout en prévenant sa rupture au cours de l'étincelage. Application : usinage par électro-érosion.According to this method, an electrode-part 2 is cut by means of a tool electrode 1 in the form of a wire, successive current pulses are passed through the spark space between the wire 1 and the part 2, this wire 1 is moved longitudinally in the machining zone 3 by subjecting it to a determined tensile force. The electrical resistance of the wire is measured in the part of this wire 1 which passes through the machining zone 3, and the machining current and / or the tensile force exerted on this wire 1 in this zone 3 are adjusted so as to maintain this electrical resistance at predetermined values. This adjustment ensures permanent control of the mechanical and thermal stresses exerted on the wire 1 while preventing its breakage during sparking. Application: machining by electro-erosion.
